College-age women represent the highest-risk age group for intimate partner violence (IPV) victimization. Bystander prevention approaches (primarily developed to address sexual assault risk on college campuses), have quickly become the mainstay of primary prevention education for gender-based violence in these settings and have been applied to all forms of gender violence in this setting, including IPV. The purpose of this paper is to critically examine the application of bystander approaches to prevention of IPV among college students. A brief overview of the current policy environment mandating prevention education will precede a summary of the conceptual framework underpinning bystander approaches to preventing and responding to sexual violence, followed by an analysis of how IPV does (and does not) fit within that same conceptual framework. The paper concludes with recommendations informal social network-informed approaches to dating violence that improve our theoretical understanding of IPV prevention on college campuses.
